Abstract

PURPOSE: To obtain an oil of a high sepn. degree and high oil pressure by installing feed blades on the outside of the porous layer of a annular rotor to be driven in compliance with the contour of an annular space spreading in a conical shape and providing this annular space with a mixture supply port and an oil discharge port. CONSTITUTION: The oil-air mixture flows through a passage 10 and an oil feed port 2 into a region 16 and is accelerated by the feed blades 3, and is centrifugally separated toward the outside wall 1 of the annular chamber 13. The mixture is then sent to the oil discharge port 5 along the conical outside wall 1. The air pressure in the annular space 13 is increased and the air between holding rings 12a and b is sucked into the porous layer 14. The air arrives at an inside chamber 17 through the holes 15 of the rotor 9 and is discharged from an opening 18.

In that case, the oil forms a layer and is sent further to the oil outlet. If the oil outlet or the conduit following it has a certain level of stagnation (Riic

The air mixture flows through a cylindrical rotating perforated matrix (Ma
Oil-air separators are known that flow through a trix). However, in this case there is no clear separation between the oil and air feed, so that the air flow accompanies the oil particles.

。ｊによって解決される。[Means and effects for solving the problem] This problem is solved by the present invention, which has a driven perforated rotor formed as a hollow cylinder in a stator casing, and through a layer of the perforated rotor. It is provided with an annular chamber through which the separated air can enter the rotor interior space and which extends radially outward of said layer, said annular chamber having an inlet 2 for the oil-air mixture and a separate outlet for the oil. 5, a plurality of feed vanes 3 oriented radially outward from the core layer are mounted on the rotor 9 radially outward of the perforated layer 14, the feed vanes directing the flow An oil-air separator characterized in that it is adapted to the contour of said annular chamber 13 which widens conically in the direction.

される。This advantageously achieves that the oil is accelerated by the feed vanes during its entire path in the annular chamber. The arrangement of the oil supply and outlet ports at the ends of the annular chamber axially apart frees up long acceleration paths. Furthermore, the constant radial acceleration by the feed vanes causes the oil flow to flow along the annular wall, so that a larger amount of oil is prevented from penetrating radially inwardly in the perforated layer. The continuous blade feeding along the annular chamber prevents the formation of many oil springs.

圧力が生じるので、有利に働く。The acceleration energy supplied to the oil flow in its path through the annular chamber acts as a higher static pressure on the oil outlet, which reduces the risk of clogging and ensures a reliable feeding action as well as Oil cooler and water pressure pump are free. This is particularly advantageous in the case of aircraft engines, since sufficient supply pressure is available in all flight positions.

る。In a further preferred embodiment of the invention, a cover that runs together radially outwardly is fixed to the plurality of feed vanes. In this way, a film of oil can be applied along the inner surface of the rotating shroud, so that in particular even higher pressures are generated and oil springs are avoided. In addition to this, the power required to drive the rotor is reduced, since friction at the fixed outer sheath of the rotating oil is eliminated.

Located at the downstream end of the annular chamber 13 is an oil capture ring 23 of the casing 7 in which the incoming oil flow is collected and directed to the oil outlet 5. During operation, a stagnation is provided in the oil drain conduit (not shown) so that the oil capture ring 23 remains partially filled with oil.
